I also had lots of problem activating my iPhone and then I had some troubleshooting problems as well. I actually found a great site the helped me, Here is the page for iPhone Support:

I had problems as well its too bad they didn't do it before, I already opened my consoled and fixed it myself. But if it will happen again I will not have a warranty.

I did find a great site that help you fix it:

I had the same problem and it was bugging me for a long time. Recently I found a great tech support site with free live chat support and guaranteed solutions. Here is the page for Xbox 360 repair

Good luck
